But as two best friends discover, the light of that miracle may be blinding the world to its horrors.Chance and Leap are jolted out of their professional routines by a terrifying stranger—a remorseless killer who freely manipulates the networks that regulate life in the post-Join world. Their quest for answers—and survival—brings them from the networks and spire communities they’ve known to the scarred heart of an environmentally ravaged North American continent and an underground community of the “ferals” left behind by the rush of technology.In the storytelling tradition of classic speculative fiction from writers like David Mitchell and Michael Chabon, Join offers a pulse-pounding story that poses the largest possible questions: How long can human life be sustained on our planet in the face of environmental catastrophe? What does it mean to be human, and what happens when humanity takes the next step in its evolution? If the individual mind becomes obsolete, what have we lost and gained, and what is still worth fighting for?

    It causes people to forget—small things at first, like where they left their keys…then the not-so-small things like how to drive, or the letters of the alphabet. Then their bodies forget how to function involuntarily…and there is no cure. But now, far below the surface of the Pacific Ocean, deep in the Marianas Trench, an heretofore unknown substance hailed as “ambrosia” has been discovered—a universal healer, from initial reports. It may just be the key to a universal cure. In order to study this phenomenon, a special research lab, the Trieste, has been built eight miles under the sea’s surface. But now the station is incommunicado, and it’s up to a brave few to descend through the lightless fathoms in hopes of unraveling the mysteries lurking at those crushing depths…and perhaps to encounter an evil blacker than anything one could possibly imagine.

    For five years the people of the U.S. Virgin Islands have lived with the Ynaa, a race of super-advanced aliens on a research mission they will not fully disclose. They are benevolent in many ways but meet any act of aggression with disproportional wrath. This has led to a strained relationship between the Ynaa and the local Virgin Islanders and a peace that cannot last. A year after the death of a young boy at the hands of an Ynaa, three families find themselves at the center of the inevitable conflict, witness and victim to events that will touch everyone and teach a terrible lesson.
